3 percent Medium Expansion Foam Fire Extinguishing Agent

3% Medium Expansion Foam Fire Extinguishing Agent

Product overview:

The medium expansion foam fire extinguishing agent is made of foaming agent, cosolvent, stabilizer, freezing resistance agent, and water. Due to the unique properties of medium expansion foam, its Foaming expansion rate is larger than that of low expansion foam, while the foaming mass is heavier than that of high expansion foam, therefore, in addition to the fire prevention and extinguishing of underground tunnels, airplane hangars, coal mines, underground garages, oil depots, ships and underground confined space, and it also can play a more important role in covering large areas of non-aqueous-soluble combustible and flammable flowing liquid.
